When you insert an audio clip into a PowerPoint slide, you can
control its volume, set it to play looped, or even hide the audio icon. These are some of the advanced options available for any inserted audio clip
in PowerPoint. Remember that these advanced options only exist so that you can use them when they are required, rather than using them just because
they exist! Let us now explore all these options:

Open your presentation, and navigate to the required slide where you have already
inserted an audio clip. Select or double-click the audio clip to
bring up the two contextual Audio Tools tabs in the Ribbon.
These two tabs are Format and Playback -- click the Playback tab to activate it, as shown
highlighted in red within Figure 1.

Within the Audio Tools Playback tab, locate the Audio Options group, as shown in Figure 2.

Within this group you'll find the advanced audio options. Let us explore them as marked in Figure 2 above:

Volume: This button enables you to set the volume for your audio clip. Click the downward arrow within the
Volume button to open the Volume drop-down gallery, as shown in Figure 3. Within the
Volume drop-down gallery choose one of the following options: Low, Medium, High,
and Mute.

Note that you are restricted to set the volume at only the Low, Medium, and High levels within the
Volume drop-down gallery. On the other hand, you can set the volume to whichever level you want by clicking on the
Volume button on the Player Controls bar below the actual audio clip on the slide, as shown in the bottom right of
Figure 4, below.

Start: Here you can specify how you want your audio to start during your presentation. Click the Start list to
bring up a drop-down list, as shown in Figure 5.

There are three options within the Start drop-down list:

Automatically: Play your audio when the slide (containing the audio) appears in
Slide Show view, automatically.

On Click: Plays your audio by clicking on the audio itself in
Slide Show view.

Loop until Stopped: Plays your audio repeatedly and continuously when the active slide is shown.

Hide During Show: Select this check-box to hide your audio clip graphic in
Slide Show view. This option makes sense only if you set the
Start option for the audio to be Automatically or Play across Slides. On the other hand, if you
choose On Click, you should never pair that with selecting the Hide During Show check-box -- if you do so, you won't
be able to see anything you can click!

Rewind after Playing: Select this check-box to rewind your audio once it has played during your presentation. This can be useful
if you need to play an audio clip more than once while you are still presenting the same slide which contains that audio clip.

Choose options based on your requirements. Make sure you save your presentation.
